DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 and 2, which show a method of the present invention for inserting a radio frequency identification tag into an optical disc. Firstly a set of base plates 1 and a radio frequency identification tag 2 are provided, and a recess 3 is further provided in the peripheries of the set of base plates 1 in order to insert the radio frequency identification tag 2 therein.
As shown in FIGS. 1 and 3-5, which show the first embodiment of the present invention, the method process includes the following steps:
- a. providing firstly a set of base plates and a radio frequency identification tag, filling adhesive at a central region between the set of base plates, and providing a recess of the peripheries of the set of base plates;
- b. inserting the radio frequency identification tag into the recess of the peripheries of the set of base plates;
- c. by rotating the set of base plates to spread the adhesive uniformly on the set of base plates from inside out and to cover the radio frequency identification tag; and
- d. curing the adhesive by irradiation of ray to combine each of the set of base plates and the inserted radio frequency identification tag.
In the step a, the used adhesive 4 has a curing feature after being irradiated by ray and the chosen ray is ultraviolet ray or any kind of light beams able to have the effect of curing after being irradiated. The radio frequency identification tag 2 comprises a chip 21 and an antenna 22 extending outwards from of the two lateral sides of the chip 21. The set of base plates 1 comprise an upper base plate 11 and a lower base plate 12; and the upper and lower base plate 11 and 12 comprise respectively upper and lower surfaces 111, 112, 121 and 122. A notch 113 and 123 are respectively provided of the periphery of the lower surface 112 of the upper base plate 11 and the periphery of the upper surface 121 of the lower base plate 12. The two notches 113 and 123 together form the recess 3. The recess 3 can also be provided solely on the periphery of the lower surface 112 of the upper base plate 11 (as shown in FIG. 6) or on the periphery of the upper surface 121 of the lower base plate 12. The shape of the recess 3 is not limited to the rectangular shape depicted in the accompanying drawings, it can also be arc-form, a V shape or any other shapes able to cover or receive the shape of the radio frequency identification tag 2.
In the step b, when the radio frequency identification tag 2 is inserted into the recess 3 of the peripheries of the set of base plates 1, the antenna 22 at the two lateral sides of the chip 21 separately arcs along the peripheries of the set of base plates 1. The preferred length of the antenna 22 and the chip 21 together is a half of the peripheries of the set of base plates 1, in order to transmit, receive and read radio frequency signals in various directions.
In the step c, before combing the upper base plate 11 and lower base plate 12 to form the set of base plates 1, adhesive 4 is filled there between. Further, the set of base plates 1 are fixed on a rotate-able disk (not shown), so that when the set of base plates 1 rotate around each own axis, the adhesive 4 will be spread uniformly from inside out there between the upper base plate 11 and the lower base plate 12. In the rotation process, the upper base plate 11 presses down the lower base plate 12 by its own weight; this can increase the combining force there between the upper base plate 11 and the lower base plate 12. And in practical use, additional pressure can further put on the upper base plate 11 to make even tighter combination of the upper base plate 11 with the lower base plate 12.
Referring to FIG. 7, which is a flow chart of the method process of a second embodiment of the present invention, it comprises the following steps:
- A. providing firstly a set of base plates and a radio frequency identification tag, filling adhesive at a central region there between the set of base plates, and providing a recess of the peripheries of the set of base plates;
- B. by rotating the set of base plates to spread the adhesive uniformly from inside out of the set of base plates; and
- C. providing a partition board in advance to prevent an irradiation of ray into the recess of the peripheries of the set of base plates, curing the adhesive there between the set of base plates to combine each other, cohering the radio frequency identification tag into the recess of the peripheries of the base plates, and by an irradiation of ray, fixing the radio frequency identification tag securely therein.
As shown in FIG. 8, in the above step C, by the partition board 5, the set of base plates 1 form a light receiving surface 51 and a light un-receiving surface 52. The light un-receiving surface 52 is defined at the region above the recess 3 of the peripheries of the set of base plates 1. When the light receiving surface 51 is irradiated with a ray, the adhesive 4 there between the upper and the lower base plates 11, 12 is cured, while the adhesive 4 in the recess 3 is still in adhesively condition for allowing an insertion of the radio frequency identification tag 2. And after a second time irradiation, the adhesive 4 in the recess 3 is cured to securely fix the radio frequency identification tag 2 therein.
Referring to FIG. 9, which shows a third embodiment of the present invention, wherein the lower surface 112 of the upper base plate 11 and the upper surface 121 of the lower base plate 12 are provided inside each of them with a notch 114, 124 to receive the adhesive 4 spreading outwards during rotation of the set of base plates 1. The radio frequency identification tag 2 is spread on its surface with adhesive 6. When the radio frequency identification tag 2 is inserted into the recess 3 of the peripheries of the set of base plates 1, the radio frequency identification tag 2 can be cohered with the set of base plates 1.
In the above steps, the notches 114 and 124 can also be solely provided on either the lower surface 112 of the upper base plate 11 or the upper surface 121 of the lower base plate 12. This can also achieve the object of preventing the adhesive 4 from spreading outwards. The adhesive 6 can be filled in the recess 3 of the peripheries of the set of base plates 1 in advance and then the radio frequency identification tag 2 is inserted therein for cohesion. Further, the nature of the adhesive 6 can be same as that of the adhesive 4, i.e. when being irradiated of ray, the adhesive 6 is cured to securely fix the radio frequency identification tag 2.
Therefore, the present invention has the following advantages:
- 1. The present invention discloses a method for inserting a radio frequency identification tag into the peripheries of the set of base plates. This not only can effectively overcome the communication problem for a piled of optical discs, but also can make the radio frequency signals to be effectively received and read.
- 2. The present invention discloses a method which by rotating the set of the base plates to spread the adhesive uniformly on the set of base plates from inside out and to cover the radio frequency identification tag; further after curing of the adhesive, the radio frequency identification tag can be securely fixed in the recess. This can effectively reduce the time for spreading the adhesive to thus save cost accordingly.
- 3. The present invention has a two stages way of curing the adhesive. This not only can help the radio frequency identification tag to be inserted into the recess of the set of base plates easily, but also can securely fix the radio frequency identification tag into the recess of the peripheries of the set of base plates to increase the cohesion there between the radio frequency identification tag and the set of the base plates.
In conclusion, according to the description disclosed above, the present invention surely can achieve the expected objects thereof to provide a method of not only securely insert a radio frequency identification tag into a recess of the periphery of a optical disc, but also can surely achieve the objects of counterfeit proofing, data reading and data amending etc. in the radio frequency identification tag. Thereby the present invention is industrially useful.
